Study Goal

The goal of the study is to characterize the types of sensations produced by electrical stimulation of the spinal cord and spinal roots, as well as the effects of stimulation on phantom limb pain and your ability to control a prosthetic limb.

Study Summary

The proposed study is a pilot study to examine the perceived sensations evoked in upper-limb amputees during electrical stimulation of the spinal nerves, the effect of sensory feedback on control of a prosthetic limb, and the effect of stimulation on phantom limb pain. Results of this study will provide the foundation for future development of a neuroprosthesis to restore sensory function to individuals with upper-limb amputation, thereby increasing the functionality of prosthetic limbs and improving quality of life.
